Title: Improvements in brakes for rail vehicles
Inventor: TICKLE COLIN JOHN FREDERICK
IPC: B60T8/32
Filed: 1964-12-23
Abstract: 1,062,240. Brakes for rail vehicles; disc brakes. GIRLING Ltd. Dec. 23, 1965 [Dec. 23, 1964], No. 52358/64. Addition to 972,139. Headings F2E and F2F. In an improvement or modification of the invention described and claimed in the parent Specification, the solenoid-operated skid control valve 17 is associated not with a plurality of slave cylinders 19, but with a single slave cylinder 19<SP>1</SP> which is of the double-acting type. The rams of the cylinder 19<SP>1</SP> are coupled by suitable linkages 30 to calipers 31 co-operating with brake discs 32, one of which is associated with one of the two wheels carried by an axle of the rail vehicle. In a modification the deceleration of a wheel used by a skid detection device may be used to control the deceleration of another wheel of the vehicle. In another modification each brake on each wheel on each axle is actuated by a separate slave cylinder controlled by a separate valve actuated by a skid detection device.
Patent GB-1064980-A (GB)
Title: Method of and apparatus for electro-static successive recording of letters and printing of lines
IPC: G03G15/32
Filed: 1964-12-28
Abstract: 1,064,980. Selective printing. HITACHI Ltd. Dec. 28, 1964 [Dec. 28, 1963], No. 52533/64. Heading B6F. [Also in Division G2] An electrostatic printing machine comprises a continuously rotating type-wheel 1 from which electrostatic images are formed on an insulating surface of a tape 7, these images are powdered with ink by a magnetic bush 4 and when a complete line has travelled in front of a thin paper web 14, travelling at right angles to the tape 7, a further electrostatic discharge transfers the powder images 22 on to the web 14 at electrodes 5, 6. Previously transferred lines are shown at 23. A rotary sweeping brush 8, having soft planted hair, removes surplus ink and the tape 7 is fed away to a take-up reel 13 by feed rollers 11, 12. The web 14 may be fed continuously or step-by-step by rollers 17, 18 after passing over an electrically heated fixing roller 16. The discharge, which transfers the characters from tape 7 to web 14 occurs between the two electrodes 6, 5 to which the tape and web are held respectively by vacuum attraction. This maintains a small air gap between the two mediums and prevents smudging. The electrode 6 may extend a whole line length, part of a line, or be formed by a series of separate electrodes (Figs. 5 and 6, not shown). Machine with type arranged on a plane surface, - In a modification the type-wheel 1 is in the form of a disc, Fig. 4 (not shown), with the characters arranged on the flat surface. Type-wheel construction, printing surface and disposition of characters.-The type-wheel 1 is formed with an extension for timing marks 19, 20 representing the beginning of the character series and each character position. The type-surfaces are formed by assemblies of projecting points and since the tape 7 is continuously moving the characters are progressively axially displaced to compensate for the difference in time a selected character reaches the electrode 3 in each cycle. In the embodiment employing a type-disc, the characters are arranged on a spiral. Input arrangements.-Electric signals from a computer or the like are fed into an electronic circuit 25, Fig. 2 (not shown), which generates high and short printing pulse voltage 26 which is made to occur when the required type 2 is adjacent the electrode 3 by a combination of the input signal 24 and the synchronizing signals 19<SP>1</SP>, 20<SP>1</SP>. A tape feed pulse 21<SP>1</SP> generated by a photo-electric device and a rotary selector 21 driven in synchronism with the tape 7, together with a line-spacing pulse 24<SP>1</SP>, the start pulse 19<SP>1</SP>, control a second electronic circuit 27 to apply a short and high pulse voltage 28 across the electrodes 5 and 6 to transfer the images from the tape 7 to the web 14.

Abstract: 1373217 Making A.C. generator rotors ROBERT BOSCH GmbH 24 Nov 1971 [25 Nov 1970] 54484/71 Heading B3A A method of making a core for an A.C. generator comprises providing flat iron plate material having a width corresponding to the axial length of a finished core, bending the ends of the flat iron plate material, then working the material into a cylindrical hollow member having inner and outer diameters corresponding to the dimensions of a finished core, inserting a mandrel into the member, drawing the outer diameter of the member down to a size corresponding to the external diameter of a finished core, applying axial pressure to press the member to the axial length of a finished core and allowing any excess material to form a bead 15, Fig. 8, on the outer periphery of the member and removing the bead in a final work stage. In bending the plate material, its ends are first bent through 90 degrees, Fig. 2a (not shown), then it is formed into an open hollow member (11b), Fig. 3b (not shown), and finally rolled into the cylindrical hollow member. Two plates may be similarly formed into members 12a, 12b, which are assembled together prior to drawing down. The cylindrical member is drawn down in a tapered die which is provided with an an nular recess into which the excess material flows to form the bead 15. In making a rotor for an A.C. single or three-phase generator, the winding is applied peripherally of the core and concentric grooves may be formed in the end faces of the core when it is pressed to its final length. Magnetic polepieces may be pressed against the end of the core to establish a magnetic path substantially free from air gaps.

Abstract: 1369627 Printed circuits HITACHI Ltd 7 Dec 1971 [18 Dec 1970] 56768/71 Heading H1R A method of manufacturing a printed ceramic substrate comprises the steps of forming a conductor pattern on a green ceramic sheet, printing a green ceramic film on selected areas of said conductor pattern and green ceramic sheet, forming a second conductor pattern on said green ceramic film, and providing further ceramic films and conductor patterns if necessary, the resultant assembly then being sintered to form a monolithic structure. In one embodiment manganese, molybdenum or tungsten conductors 12, 13 and 14, Figs. 2C and 3, are silk screened on to an alumina sheet 11 and an annular green ceramic film 15 is silk screened on to - selected areas on the conductors 12 and 13 and green ceramic sheet 11. A second molybdenum or tungsten layer 16 is formed on the annular ceramic film 15 after which the assembly is heated in a reducing atmosphere to sinter the ceramic layers and metal conductors. The substrate so produced may then be used in a packaged integrated circuit, the electrodes of a semi-conductor chip mounted on the circular conductor pad 14 and external leads being connected to the inner and outer ends of conductors 12 and 13. The chip may be hermetically sealed by means of a Kovar cover-plate welded to a Kovar ring soldered to the annular conductor 16. In a second embodiment, Fig. 4B, an alumina/ magnesia/silica sheet 21 provided with holes 22 for use in alignment has Mo or W interconnection layers, e.g. 29, printed on the surface, portions of said interconnection layers being covered by a printed green ceramic film 40 with openings 41 to expose terminals of the layers.

A further metal layer, of similar shape but smaller area, is then screen printed on to film 55. The substrate thus produced is then sintered in an N 2  or H 2 /N 2  atmosphere and used to form a  packaged integrated circuit, as before. The ceramic used may alternatively be silica or beryllia. Reference has been directed by the Comptroller to Specification 1,255,253.
